this isn't an axis question (despite the subject) it's a
string-value-of-nodeset question.

  <xsl:template match="tag">
      <xsl:value-of select="@name"/>
  </xsl:template match>

  I get both of them:

here the template fires on each tag element, and each time the @name
expression is evaluated. So you get the value of the name attribute in
each case:

greedylonely


  <xsl:template match="tag">
      <xsl:value-of select="../tag/@name"/>
  </xsl:template match>

here you evaluate the expression ../tag/@name which returns a node set
of all the name attribute nodes of tag children of your parent.
you then execute value-of which makes the string value of whatever
expression is selected. The string value of a node set is the character
data in (all the descendents of) the first node in the set.
so in this case that is greedy, so you get that twice.
